我矿565米中段的涌水从0963~#回风井引下至450米中段,再由水沟排出地表。565米中段的涌水量为0.16～0.35m~3/s。流量大,落差高,造成该回风天井的风流反向,烟尘下行,严重扰乱了通风系统。为了克服反向风压,我们构想了利用水流压头进行循环通风并和主扇有机结合的方案。一、涌水水流对通风系统的影响我矿通风方式为中央进风、两翼抽出式分区通风(如图1)。两台主扇工作方式均为抽出式。单翼最大需风量为35m~3/s,满足排尘风量19m~3/s的要求。
The gushing water in the middle section of mine 565 meters leads down to the middle section of 450 meters from 0963 ~ # return air shaft, and then drains the surface from the ditch. The influx of 565 meters in the middle of 0.16 ~ 0.35m ~ 3 / s. Large flow, high drop, resulting in the return of the return air flow courtyard, soot downstream, seriously disrupting the ventilation system. In order to overcome the reverse wind pressure, we envisaged the use of water pressure head circulation ventilation and the main fan organic combination of programs. First, the impact of gushing water on the ventilation system Mine ventilation for the central air inlet, wings out of the type of ventilation (Figure 1). Two main fan working methods are drawn. The maximum required air volume of the wing is 35m ~ 3 / s, which meets the requirements of 19m ~ 3 / s dust discharge air volume.
